I have a slightly overclocked Core i5 3570k (3.8mhz clocked up to 4.22mhz). Its normally sits around the 30 degree mark when idle and around the mid 50s to mid 60's when gaming. But when I torture tested it under Prime 95 core 1 occasionally goes up to 81 degrees, though most of them sit around the mind 70's. Should I be worried?
